The increasing consumption of antibiotics by humans and animals and their inappropriate disposal have increased antibiotic load in municipal and pharmaceutical industry waste, resulting in severe public health risks worldwide. Anaerobic digestion (AD) is the main force of antibiotic-containing wastewater treatment, and the adaptability of biochar/hydrochar (BC/HC) makes it an attractive addition to AD systems, which aim to promote methane production efficiency. Nevertheless, further studies are needed to better understand the multifaceted function of BC/HC and its role in antibiotic-containing wastewater AD. This review article examines the current status of AD of antibiotic-containing wastewater and the effects of different preparation conditions on the physicochemical properties of BC/HC and AD status. The incorporation of BC/HC into the AD process has several potential benefits, contingent upon the physical and chemical properties of BC/HC. These benefits include mitigation of antibiotic toxicity, establishment of a stable system, enrichment of functional microorganisms and enhancement of direct interspecies electron transfer. The mechanism by which BC/HC enhances the AD of antibiotic-containing wastewater, with focus on microbial enhancement, was analysed. A review of the literature revealed that the challenge of optimization and process improvement must be addressed to enhance efficiency and clarify the mechanism of BC/HC in the AD of antibiotic-containing wastewater. This review aims to provide significant insights and details into the BC/HC-enhanced AD of antibiotic-containing wastewater.
人类和动物对抗生素的消耗量不断增加，以及抗生素的不当处置，增加了城市和制药行业废物中的抗生素负荷，给全球公共卫生带来了严重风险。厌氧消化（AD）是含抗生素废水处理的主要手段，生物炭/水热炭（BC/HC）的适应性使其成为AD系统中颇具吸引力的添加物，旨在提高甲烷生产效率。然而，需要进一步研究以更好地理解BC/HC的多方面功能及其在含抗生素废水AD中的作用。这篇综述文章考察了含抗生素废水AD的现状以及不同制备条件对BC/HC物理化学性质和AD状况的影响。将BC/HC纳入AD过程有几个潜在益处，这取决于BC/HC的物理和化学性质。这些益处包括减轻抗生素毒性、建立稳定系统、富集功能微生物以及增强种间直接电子转移。分析了BC/HC增强含抗生素废水AD的机制，重点是微生物增强作用。对文献的综述表明，必须应对优化和工艺改进方面的挑战，以提高效率并阐明BC/HC在含抗生素废水AD中的作用机制。这篇综述旨在为BC/HC增强含抗生素废水的AD提供重要见解和详细信息。
